旋转式井壁取心器（简称ＲＳＣＦ）是应用液压原理，推进旋转的钻头完成取心过程，由于该类取心器较少破坏地层，所取岩心颗粒完整，极具实验和分析价值，因此近年来愈来愈受到勘探地质部门重视。总结过去操作与维修的经验，虽然旋转式井壁取心器较爆炸撞击式取心器先进许多，但也有值得深入研究的地方。文章从仪器密封安全性能、钻进遇卡自解以及模拟信号数字化等几个方面进一步探讨完善旋转式井壁取心器综合性能的有效途径。
Rotary shaft heartbolt (referred to as RSCF) is the application of hydraulic principles, the rotation of the drill bit to complete the coring process, as less damage to the formation of such coring device, the core particles taken complete, very experimental and analytical value, therefore In recent years, more and more attention by the exploration geology department. Summing up the past experience in operation and maintenance, although rotary wellbore coring tools are much more advanced than those of explosive impact concentrators, there are also areas worth further study. This article further explores the effective ways of improving the comprehensive performance of rotary wellbore take-off from several aspects such as the safety performance of instrument sealing, self-solution of stuck-in-card and digitization of analog signal.
